OpenAI has scheduled a livestream for 7 Aug 2025 at 10 a.m. Pacific Time, posting the phrase “LIVE5TREAM THURSDAY 10AM PT” on its social-media channels—an explicit hint that the company will unveil its long-awaited GPT-5 large language model. Chief Executive Officer Sam Altman has been previewing the upgrade for weeks, sharing a screenshot labelled “ChatGPT 5” and saying the firm has “a ton of stuff to launch.” Boris Power, head of applied research, added that he is “excited to see how the public receives GPT-5.” Microsoft, OpenAI’s largest backer, has been expanding server capacity in anticipation of the rollout, according to reporting by The Verge. If confirmed, GPT-5 would be the first flagship model since GPT-4 debuted in March 2023. Reuters reporting cited by Forbes México says early testers found notable gains in coding and problem-solving, though the leap from GPT-4 to GPT-5 may be less dramatic than the previous generation. Industry outlets including TechRadar and Tom’s Guide expect the new system to feature faster performance, improved memory and automatic routing between specialised sub-models. The event caps a busy week for the San Francisco-based company, which on 5 Aug released two open-weight models—gpt-oss-120b and gpt-oss-20b—that can run locally on consumer hardware. Altman has cautioned users to expect temporary “capacity crunches” as millions attempt to access the new services once the livestream concludes.
